Lalit's average earning per month in the first three months of a year was ₹4184. In April, his earning was 50% more than the average earning in the first three months. If his average earning per month for the whole year is ₹17553, then what will be Lalit's average earning (in ₹) per month from May to December?

Correct option is C

Given:

Average earning for first three months = ₹4184

April's earning = 150% of ₹4184 (50% more)

Average earning for the whole year = ₹17553

Concept Used:

Total earnings = Average earning $$\times$$​ Number of months

Solution:

Total earning for the first three months:

3 $$\times$$₹4184 = ₹12552​

April's earning:

1.50$$\times$$₹4184 = ₹6276​

Total earning for the whole year:

12 $$\times$$ ₹17553 = ₹210636​

Total earning from May to December:

₹210636 - ₹12552 - ₹6276 = ₹191808

Average earning from May to December:

​$$\frac{₹191808 }{ 8}$$​ = ₹23976

Option (C) is right.
